Time flies when you're having fun..

Daniel was having such a good time in Rebecca's body masturbating with her giant dildo that he did not notice until 4 hours after the swap back deadline had past that she had not returned with his body and he was now stuck like this forever.

Which was something he definitely did not want to be as it was one thing spending a day as a woman having fun it was a whole nother thingspending the rest of your life as one.
